The value of this configuration should be between zero and two. The port must have been initialised by the boot-loader before use. config SAMSUNG_ATAGS def_bool n depends on !ARCH_MULTIPLATFORM depends on ATAGS help This option enables ATAGS based boot support code for Samsung platforms, including static platform devices, legacy clock, timer and interrupt initialization, etc. Platforms that support only DT based boot need not to select this option. if SAMSUNG_ATAGS config S3C_GPIO_SPACE int "Space between gpio banks" default 0 help Add a number of spare GPIO entries between each bank for debugging purposes. This allows any problems where an counter overflows from one bank to another to be caught, at the expense of using a little more memory. config S3C_GPIO_TRACK bool help Internal configuration option to enable the s3c specific gpio chip tracking if the platform requires it. # ADC driver config S3C_ADC bool "ADC common driver support" help Core support for the ADC block found in the Samsung SoC systems for drivers such as the touchscreen and hwmon to use to share this resource. # device definitions to compile in config S3C_DEV_HSMMC bool help Compile in platform device definitions for HSMMC code config S3C_DEV_HSMMC1 bool help Compile in platform device definitions for HSMMC channel 1 config S3C_DEV_HSMMC2 bool help Compile in platform device definitions for HSMMC channel 2 config S3C_DEV_HSMMC3 bool help Compile in platform device definitions for HSMMC channel 3 config S3C_DEV_HWMON bool help Compile in platform device definitions for HWMON config S3C_DEV_I2C1 bool help Compile in platform device definitions for I2C channel 1 config S3C_DEV_I2C2 bool help Compile in platform device definitions for I2C channel 2 config S3C_DEV_I2C3 bool help Compile in platform device definition for I2C controller 3 config S3C_DEV_I2C4 bool help Compile in platform device definition for I2C controller 4 config S3C_DEV_I2C5 bool help Compile in platform device definition for I2C controller 5 config S3C_DEV_I2C6 bool help Compile in platform device definition for I2C controller 6 config S3C_DEV_I2C7 bool help Compile in platform device definition for I2C controller 7 config S3C_DEV_FB bool help Compile in platform device definition for framebuffer config S3C_DEV_USB_HOST bool help Compile in platform device definition for USB host. config S3C_DEV_USB_HSOTG bool help Compile in platform device definition for USB high-speed OtG config S3C_DEV_WDT bool default y if ARCH_S3C24XX help Complie in platform device definition for Watchdog Timer config S3C_DEV_NAND bool help Compile in platform device definition for NAND controller config S3C_DEV_ONENAND bool help Compile in platform device definition for OneNAND controller config S3C_DEV_RTC bool help Complie in platform device definition for RTC config SAMSUNG_DEV_ADC bool help Compile in platform device definition for ADC controller config SAMSUNG_DEV_IDE bool help Compile in platform device definitions for IDE config S3C64XX_DEV_SPI0 bool help Compile in platform device definitions for S3C64XX's type SPI controller 0 config S3C64XX_DEV_SPI1 bool help Compile in platform device definitions for S3C64XX's type SPI controller 1 config S3C64XX_DEV_SPI2 bool help Compile in platform device definitions for S3C64XX's type SPI controller 2 config SAMSUNG_DEV_TS bool help Common in platform device definitions for touchscreen device config SAMSUNG_DEV_KEYPAD bool help Compile in platform device definitions for keypad config SAMSUNG_DEV_PWM bool default y if ARCH_S3C24XX help Compile in platform device definition for PWM Timer config SAMSUNG_DEV_BACKLIGHT bool depends on SAMSUNG_DEV_PWM help Compile in platform device definition LCD backlight with PWM Timer config S3C24XX_PWM bool "PWM device support" select PWM select PWM_SAMSUNG help Support for exporting the PWM timer blocks via the pwm device system config S3C_SETUP_CAMIF bool help Compile in common setup code for S3C CAMIF devices config SAMSUNG_PM_GPIO bool default y if GPIO_SAMSUNG && PM help Include legacy GPIO power management code for platforms not using pinctrl-samsung driver. endif config S5P_DEV_MFC bool help Compile in setup memory (init) code for MFC comment "Power management" config SAMSUNG_PM_DEBUG bool "Samsung PM Suspend debug" depends on PM && DEBUG_KERNEL depends on DEBUG_EXYNOS_UART || DEBUG_S3C24XX_UART || DEBUG_S3C2410_UART help Say Y here if you want verbose debugging from the PM Suspend and Resume code. See for more information. config S3C_PM_DEBUG_LED_SMDK bool "SMDK LED suspend/resume debugging" depends on PM && (MACH_SMDK6410) help Say Y here to enable the use of the SMDK LEDs on the baseboard for debugging of the state of the suspend and resume process. Note, this currently only works for S3C64XX based SMDK boards. config SAMSUNG_PM_CHECK bool "S3C2410 PM Suspend Memory CRC" depends on PM select CRC32 help Enable the PM code's memory area checksum over sleep. This option will generate CRCs of all blocks of memory, and store them before going to sleep. The blocks are then checked on resume for any errors. Note, this can take several seconds depending on memory size and CPU speed. See config SAMSUNG_PM_CHECK_CHUNKSIZE int "S3C2410 PM Suspend CRC Chunksize (KiB)" depends on PM && SAMSUNG_PM_CHECK default 64 help Set the chunksize in Kilobytes of the CRC for checking memory corruption over suspend and resume. A smaller value will mean that the CRC data block will take more memory, but wil identify any faults with better precision. See config SAMSUNG_WAKEMASK bool depends on PM help Compile support for wakeup-mask controls found on the S3C6400 and above. This code allows a set of interrupt to wakeup-mask mappings. See config SAMSUNG_WDT_RESET bool help Compile support for system restart by triggering watchdog reset. Used on SoCs that do not provide dedicated reset control. config DEBUG_S3C_UART depends on PLAT_SAMSUNG int default "0" if DEBUG_S3C_UART0 default "1" if DEBUG_S3C_UART1 default "2" if DEBUG_S3C_UART2 default "3" if DEBUG_S3C_UART3 endmenu endif
